use macOS terminal can not install MicroPython on Raspberry Pi Pico bug All In One

使用 macOS 终端无法在 Raspberry Pi Pico 上安装 MicroPython bug

MicroPython 环境搭建

您可以通过 USB 将 Pico 连接到计算机，然后将文件拖放到它上面来对 Pico 进行编程，因此我们整理了一个可下载的 UF2 文件，让您可以更轻松地安装 MicroPython。

Welcome to MicroPython!

For online help please visit https://micropython.org/help/.

For access to the hardware use the 'machine' module.  RP2 specific commands
are in the 'rp2' module.

Quick overview of some objects:
  machine.Pin(pin) -- get a pin, eg machine.Pin(0)
  machine.Pin(pin, m, [p]) -- get a pin and configure it for IO mode m, pull mode p
    methods: init(..), value([v]), high(), low(), irq(handler)
  machine.ADC(pin) -- make an analog object from a pin
    methods: read_u16()
  machine.PWM(pin) -- make a PWM object from a pin
    methods: deinit(), freq([f]), duty_u16([d]), duty_ns([d])
  machine.I2C(id) -- create an I2C object (id=0,1)
    methods: readfrom(addr, buf, stop=True), writeto(addr, buf, stop=True)
             readfrom_mem(addr, memaddr, arg), writeto_mem(addr, memaddr, arg)
  machine.SPI(id, baudrate=1000000) -- create an SPI object (id=0,1)
    methods: read(nbytes, write=0x00), write(buf), write_readinto(wr_buf, rd_buf)
  machine.Timer(freq, callback) -- create a software timer object
    eg: machine.Timer(freq=1, callback=lambda t:print(t))

Pins are numbered 0-29, and 26-29 have ADC capabilities
Pin IO modes are: Pin.IN, Pin.OUT, Pin.ALT
Pin pull modes are: Pin.PULL_UP, Pin.PULL_DOWN

Useful control commands:
  CTRL-C -- interrupt a running program
  CTRL-D -- on a blank line, do a soft reset of the board
  CTRL-E -- on a blank line, enter paste mode

For further help on a specific object, type help(obj)
For a list of available modules, type help('modules')

minicom

Minicom is a text-based modem control and terminal emulator program for Unix-like operating systems, originally written by Miquel van Smoorenburg, and modeled somewhat after the popular MS-DOS program Telix but is open source.

Minicom 是用于类 Unix 操作系统的基于文本的调制解调器控制和终端仿真器程序，最初由 Miquel van Smoorenburg 编写，有点模仿流行的 MS-DOS 程序 Telix，但它是开源的。

raspi-config

# GUI 交互式命令行界面
$ sudo raspi-config

在本质上还是直接修改 /boot/config.txt 配置文件
